Am I eligible?

Most Queensland homes and small businesses are.

There’s no means test, and you don’t need to apply yourself. We check eligibility and handle the claim as part of your quote.

Off-grid properties can claim the rebate too.

  • An approved battery between 5 kWh and 100 kWh, on the Clean Energy Council approved list
  • An SAA-accredited installer. That’s us.
  • VPP-capable for grid-connected homes. The battery or inverter must be able to join a virtual power plant. Joining one is your choice.
  • Solar, new or existing. Adding a battery to the solar you already have is eligible.

Questions

Battery rebate FAQs

Can’t see your question? Call Ryan on 0456 000 876.

Is there a Queensland battery rebate as well?

Not at the moment. Queensland’s Battery Booster program closed in 2024. The federal rebate is the main incentive available now.

Do I have to join a virtual power plant?

No. The battery or inverter must be able to join one, but joining is your choice.

Can I add a battery to my existing solar?

Yes. Battery-only installs on existing solar are eligible. We’ll check your current system is suitable.

Does the rebate apply to off-grid systems?

Yes, off-grid battery systems are eligible too.

What size battery should I get?

For most homes, 10 to 14 kWh is the sweet spot because it gets the full rebate rate. We size it from your actual usage, not a sales target.

When do I get the money?

You don’t wait for anything. The rebate is taken off your quote up front.
